Infrastructure
Bunker infrastructure includes the physical resources that support your instances.
Overview
Infrastructure is organized in three levels:
- Datacenters - Physical data centers in Europe
- Networks - Connectivity and isolation
- Storage - Data persistence
Architecture
Datacenters
All Bunker datacenters are located in Europe:
| Datacenter | Location | Compliance |
|---|---|---|
| DC01 | Les Essarts-en-Bocage (Vendée, France) | Sovereign France, GDPR compliant |
| DC02 | Rennes (Ille-et-Vilaine, France) | Sovereign France, GDPR compliant |
| DC03 | Nantes (Loire-Atlantique, France) | Sovereign France, GDPR compliant |
| DC04 | Challans (Vendée, France) | Sovereign France, GDPR compliant |
Characteristics
- Power: N+1 redundancy
- Cooling: Free cooling + air conditioning
- Security: Biometric access, 24/7 video surveillance
- Network: Multiple carriers, low latency
Networks
Private Network
Each project has an isolated private network:
- Configurable address range
- Complete isolation between projects
- Optimized internal routing
Inter-DC connectivity
Datacenters are interconnected through two complementary encryption layers:
- IPsec tunnels between each DC pair, leveraging hardware-accelerated AES encryption (AES-NI)
- Headscale (built on WireGuard with ChaCha20-Poly1305 encryption) for Zero Trust networking and access management
Public Network
Instances can be exposed on the Internet via:
- Dedicated public IP - Fixed address
- Load Balancer - Load distribution
Storage
Bunker uses Ceph for distributed storage:
| Type | Usage | Performance |
|---|---|---|
| SSD NVMe | System, databases | Ultra-fast |
| HDD | Archives, backups | Economical |
Characteristics
- Replication: Minimum 3 copies
- Encryption: In transit and at rest on the storage layer
- Snapshots: Instant snapshots for backup
Data Location
In accordance with our sovereignty commitment:
- All data stays in Europe
- No replication abroad
- Hosting under European jurisdiction
Management via Control Plane
The Control Plane API exposes an Infrastructure service to:
- List available datacenters
- Manage network resources
- Provision storage
Next Steps
- Hypervisors - Understand virtualization
- Instances - Create virtual machines
